In a way, the mustache line also ties back to the airbender sideshow act he put on where they picked up Kai. He was wearing a false mustache there.

I expect they'll be happy to once airbenders are definitely established as a "thing" again. After all, even more bending forms equals even more excitement.

Zhu Li's body language when Varrick told her to clean up the mess he'd just made was priceless. This show is terrific with the comedy beats.

Did anyone notice that thing Tenzin was having them do with the feather while balancing was basically the same thing as Aang's marble trick from "Warriors of Kyoshi"? Presumably a feather would be easier to keep aloft than a marble…

Maybe they were observing some kind of holiday during which they all return to the temples.

Except that Aang wasn't secluded from the rest of the world. He had apparently traveled quite a lot, before there was even the possibility he was the Avatar. He seemed to know a lot about the world (or, at least, the world as it was in his day), even down to the latest (well, latest a hundred years ago) Fire Nation…

Yeah. You know, before the show aired, I had to admit I had my doubts that Aang's son, the successor to the cultural legacy of the Air Nomads, was going to be played by the same actor as J. Jonah Jameson and Portal's Cave Johnson. But he's done the most amazing job.

No reason to expect the guy was telling the truth. Hell, Bosco was probably long dead by the time the Earth Queen came to power. Bears don't live as long as humans, y'know.

Something I really liked was the change in Lin's voice after the fight. So much of the bitterness was gone. She didn't sound quite so grumpy anymore. Seems as though she'd been carrying a lot of repressed anger, and her personality is rather different now that it's gone. I'll be interested to see if this difference…
